Ringold, Shrewsbury, Mass, assignors, by mesne assignments, to Syntax Corporation, a corporation of Panama No Drawing. Filed Mar. 24, 1961, Ser. No. 98,018 20 Claims. (Cl. 269-2395) resented by the following formulas:

III IV In the above formulas X represents either a double bond or a saturated linkage and in this case the compounds may be C5 normal or allo. R represents either the isonicotinylhydrazide residue of the following formula:

| CONHN 5 or the nicotinylhydrazide residue of the followmg formula:

I C O NHN R represents either residue of nicotinylhydrazine of the following formula:

/N U- OONELNH or the residue of isonicotinylhydrazine of the following formula:

( JONH-NH The wavy line at C-3 and C- represents either the lX- or B-configuration.

The androstane derivatives indicated .as Formulas I and II above are active hormones useful as anabolic agents since they have a favorable anabolic-androgenic ratio and are also useful as pituitary suppressant and antiestrogenic agents.

The pregnane derivatives of Formulas III and IV are anti-ovulatory agents, progestational agents, anti-estrogenic agents and anti-androgenic agents.

The novel compounds of the present invention are prepared by a process involving in general the reaction of the 3-keto group or the ZO-keto group with either isonicotinyl o-r nicotinylhydrazide to form the hydrazones of the Formulas I or III followed by reduction of the hydrazone with sodium borohydride to form the corresponding hydrazines II or IV.

The following specific examples serve to illustrate but are not intended to limit the present invention:

Example I 1 g. of allopregnan-3fi-ol-20-one and 1 g. of isonicotinylhydrazide were mixed with 20 cc. of methanol and 2 cc. of acetic acid and heated under reflux for 1 hour. After cooling, the precipitate formed was filtered, washed with methanol and dried, yielding 1.3 g. of the isonicotinylhydrazone of allopregnan-3B-ol-20-one. This compound had a melting point of 24752 C.; [aJ +20 (dioxane); A max. 268-70 m, log 5:3.99.

Example I] Treating the following ketones in exactly the same way as described in Example I, there were obtained the corresponding isonicotinylhydrazones:

M-pregnen-BB-ol-ZO-one, allopregnan c ol 2O one, pregnan-3a-ol-20-one, pregnan-Bfi-ol-ZO-one, A -androsten- 17 3-ol-3-one, testan-17B-ol-3-one (5fi-androstan-17fi-ol-3- one), androstan-l7/8-ol-3-one.

Example 111 1.12 g. of the isonicotinylhydrazone of allopregnan-3/3- ol-20-one was dissolved in a mixture of 100 cc. of tetrahydrofuran and cc. of methanol and cooled in an icebath. A solution of 1.5 g. of sodium borohydride in 15 cc. of 'water was added and the resulting mixture was kept at low temperature for 30' minutes, then overnight at room temperature. The excess reagent was neutralized with acetic acid and the solution poured into water. The precipitate formed was collected and recrystallized from acetone, thus afiording 415 mg. of a compound which had a melting point of 221-2 C.; [ot] +10 (dioxane); A max. 266-8, log e==3.72.

Chromatography afforded two products: 20a-isonicotinylhydrazo-allopregnan-3,B-ol and ZOB-isonicotinylhydrazo allopregnan-Bfi-ol.

Example 1V Following exactly the same method as described in Example III, there were reduced the isonjcotinylhydrazones set forth below, yielding the corresponding derivatives disclosed hereafter:
